I really hope you are right, Yann. Even if it isn't alumuinium, just any worthy material would be fine. Anything except this rubbish... It too was my initial thought that this stuff is just some kind of pre-cladding, but after all we have seen so far I became really pessimistic. Given they will actually cover this stuff, why wouldn't they install the final material when the panels were still on the ground? That sounds a hundred times easier than doing this in a height of up to 120 meters. Could it be that the developer himself did not decide at this time what they will do? Are they trying to cut some costs or are they unsure about the materials they could use? Time will tell... I remember we had a forumer who claimed to be an insider involved into the Ping'an south tower. It would be interesting to hear if he knows anything about the main tower and the truth about te grey cladding...!

I like how the world is changed with new and upcoming supertalls, once a time was that we have no 400m building in our earth, now we have much u/c and completed. World will totally changed, every city is coming up with new supertall. Wow nice developing.

Building higher and higher is just simply so expensive, that building 3x 150m is much more cost effective than one 450m high skyscraper. And investors in high developed world knows that, and Europe don't have a problem with lack of ground.

I want to remember you that the tallest building in Italy is the 215m tall Porta Nuova Garibaldi... And it will remain the tallest for ever... Only developing countries and just a few of the developed countries are getting taller buildings (China, USA, UAE, my beloved South Korea, Malaysia, Indonesia etc...) but European countries (excluded Russia and Turkey) aren't getting a special boom in +200m construction... 'USA and Asia is changing' is better...

Anyway that's a great tower, I really love it and I think the cladding really stand out with the surrounding and the building itself, great for Shenzhen!
